Data Trace Editor P(A-a)O2 = PAO2 – PaO2; PaO2, PaCO2: Calculated from ABG: PAO2 = (712 x FIO2) – (PaCO2/0.8); or (712-pCO2)-pO2 Normal P(A-a)O2 = 12 mm Hg in the young Adult to 20 mm Hg at age 70 yo; In pure Ventilatory Failure the P(A-a)O2 will remain 12 to 20 mm Hg; in … Read more
– optimal graft angle: – in the report by Howell SM, et al, the authors studied the angle of the tibial tunnel to graft function; – 5 surgeons treated 119 subjects by reconstructing a torn ACL using a … Read more

– Graft Entry Point: – because the slope of the intercondylar notch will vary from 26 to 44 deg, the tibial tunnel should be accordingly positioned between the anterior third and the midpoint of the saggital length of the tibia; – referenced off the PCL: – this … Read more
– Determination of Graft Length: – if a “two incision – backdoor” technique is used, it is usually not necessary to measure graft length; – whether the graft is slightly long or slightly short, it is usually very easy to move the graft slightly proximally or distally (through both … Read more
Foot Ankle Int. 1994 Jun;15(6):301-305 Friedman RL, Glisson RR, Nunley JA 2nd ABSTRACT BACKGROUND: Two commonly used techniques for tibiotalar fusion were quantitatively compared using instrumented testing of the strength of the construct. METHODS: The tibiae and tali from 10 pairs of fresh-frozen cadaveric limbs were used. One joint of each … Read more
